LED Circuit Design - How to design LED circuits

The video tutorial explains the basics of LEDs, including their properties and how they emit light. It covers the importance of using resistors to protect LEDs from excessive current and voltage, and demonstrates how to test LED circuits using a multimeter. The tutorial also discusses voltage drops across LEDs and resistors, and highlights the variations in LED characteristics. Finally, it provides example circuits and calculations for setting up LEDs with different resistors.
